AUTOMATICALLY-OPEBATENGT WEATHER STOP.

Application filed February 19, 1921.

To all whom t may concern.'

Be it known that we, JOHN Jarras Hrivrs and HENRY ROBERT WAY, citizensof Great Britain, residing at Halifax, in the Province of Nova Scotiaand Dominion of Canada, have invented new and useful improvements Stops,of' which the following is a specification.

Our present invention pertains to automatically operating weather stripstor doors, windows and the like and it contemplates the provision of adevice whereby when the window or door to which it is applied is closed,the weather strip will be automatically operated to prevent wind,draught, rain or snow from gaining access to the building or apartmentequipped with our device.

The invention also contemplates means whereby the device may be madeinoperative, such as for instance in mild or favorable weather.

The invention further contemplates the provision of a device that isreadily applied and easily removed from a door or window, and one. thatwill lend quite a 'finished appearance and harmonize rwith otherlhardware at present used by builders in producing finished andup-to-date apartments and buildings.

The invention in all of its details will be 'fully understood when readin connection with the drawings accompanying` and 'forming part of' thisspecification, in which:

Figure 1 is a perspective view illustrating our novel device as appliedto a door.

Figure 2 is a longitudinal Kectional view of the weather strip casingand illustrating the operating mechanism of the device.

Figure 3 is a sectional. view taken in the plane indicated by the line33 of Figure il looking in direction ot arrows.

Figure 4 is a view similar to Figure 3 but taken in the plane indicatedby line ot Figure 2.

Figure 5 is an end elevation ot the door showing in dotted lines portionof member The view for purposes of illustration eliminates the casing 2but discloses the trip 18 as confined between the member 3 and door 1when the door is closed.

Similar numerals of reference designate corresponding parts in all theviews ot the drawings.

The door 1 and casing 2 are of the ordi- Speciication of Letters aterit.

Serial No. 446,352.

nary well known construction and secured in the door casing 2 is a trip8.

Properly secured to the lower end of the door is the outer casing 5,having the upper flat portion in which are provided apertures for thereception of screws l or other fastening means Jfor the connection ofsaid casing to the door. This casing 5 is merely a covering :tor theworking elements ot' our invention, and may be provided with the lowerrolled portion 6. This casing nat urally is stationary.

A stationary plate 5 is also secured to the doorI through the medium otthe fastening members or screws il and rests between the casing 5 andthe door 1, and said tening` screws pass first through the casing 5 andthen through the stationary or back plate 5 and finally are secured inthe lower end of the door 1.. Secured to the back or stationary plateeither by rivets or in any approved manner are ribsv 10 that bypreterence are arranged in pairs equiedistantly throughout the lengthoi? the plate 5', and pivotally secured in the lower end oit the ribs isa rod 9 that supports the inner or movable casing 7 of my novel device.

Arranged between the series of ribs 1() are members 7 that are securedto and are movable with the rod 9 and the said members 7 form anintegral part of the movable casing 7. These members 7 are cut away nearthe upper end as illustrated in Figure 3 and pivotally secured in theupper end of the ribs 1() are alined rods 18 and 131 on each of which isprovided a member of the clutch v19. The rod 13 is surrounded by aspring .1 4 which in turn is secured at one end to the casing 7 and atits opposite end the said spring 111 is secured to a collar 1.6 tast onthe rod 13. The rod 1.31 is provided with a spring 15 and on the extremeouter end of rod 181 we produce the trip 18.

The rods 131 and 13 may be operated as a unit by turning the trip 18 tothe position shown in Figure 2 when the clutch will assume the positionshown in said figure.

Our device is simple in construction and operation and may be quicklyapplied and when building` or other structure is equipped with thedevice, draughts are precluded entering` said buildingor buildings andhence the danger of colds and diseases to the tenants of the same ismaterially decreased.

The invention `is particularly adapted for in large oifice and schoolbuildings and in company with the advantages set Vforth, it also tendsto reduce the amount otv :fuel used in heating such buildings. Moreover,dust and dirt gaining access to the building is prevented by our devicewhich. feature re-v duces the expensive outlay for labor now einployedfor cleaning a large buildinp` as well as wear on the furniture andcontents ot said building. t i

The igiullingof the rod 131 outwardly and turning of the trip 18upwardly will prevent said trip from being oiieratively engaged bymember 3 when the door is closed. The rods and 131 carry eccentrics 17that rest between the sets of ribs l and these eccentrirs 1'? areadapted to engage the cut away endetx the portions 7. As .the portionsr7" are movable `with the casing 7 and because lot the Acontact oit2these eecentrics 1.7 with the upper-end of the portions 7, cloelrwisemovement or the revolving' of the rod .13 with. respect to the lugs willnaturally impart rotary motion to the eccentrics and in turn operate thecasing' 7. The casing 'T is provided, when deemed necessary with thelower channel to `receive a strip 8 of rubber or other weatherstripping` material.

4ln the practical useol the invention, when it is desired in coldweather to employ our invention, it is siinply necessary to push the rod131,' inwardly to lock the clutch 19, The door is then closed andcontact of the trin 5% with the trip .18 will cause the cam 18 toyassume the position shown in YFigure 5. This movement of trip 18willvcause the rods 1? and 131 to rotate and the eccentricO 17 engagine' the upper ends of the portions 7 wil l manitestly tend to rotatethe casing 7 on its axis (the rod 9) and hence `the casing; will bei'orced downwardly toward the sill or Flooringand the strip o'l' rubberor other material. will snugly and iirmly tgrip said sill or floor. Uponrelease of the trip i8 `from its complementary 'trip 3, by opening ofthe door 1, the casing- 7 will be returned to its inoperative positiondue tothe action `of thesprings 1311- aiid 1 5 on rods 13 and 131 which`were under tension when the door was closed.

It will be manifest that the device is automatic in operation, and mayeither be set for use or the clutch 19 released to prevent operation ofthe device in mild-weather. It will also be. seen that because ot itsauto matic arrangement, marring of' a floor or the diiflicult opening ofthe door is eliminated and this without the necessity of manuallyreleasing the casing from its operative position.' Moreover, thisarrangement re,- lieves the necessity oli' removing,` the device in warmweatheiI and the annoying replacing' of the entire device in coldweather.

W e would distinctly have itii-ndeistood our device is so constructedthat the trip 18 simply throwing' the same so that it assumes a positionopposite that shown inFigure 5 may be prevented from operating` whendesired.

llaving describedour invention, whatwe el 'in and disire to securebylietters-Patent i i 1. .ln an automatically' operated weather stop,the combinationfof a back ilzite,` an outer stationary casingsecured tothe upper end of the back plate, a series of ribs gtormed on the backplate, rods arranged in alignment with each otherin and rotatable withrespect to the ribs, .a clutch ,adapted to couple and rotatesaid rods asa unit, cams of eccentric form arranged on the rods, meinbers movablyarranged on the lower end of the back plate and having surfaces actuableby the cams and a movable casingformed inteleral with the members; oneof saidxrods being provided with a `trip adapted to rotate the rods whenthe clutch is thrown into operative position.

2. In a device tor the. purpose set forth, the combination of a plate,aistationary casiiie Y plate. rotatable rods secured in alignment in theribs,veccentrics mounted on the rods, a clutch member arranged on eachvof the rods, said members adapted to connect said-rods to move as aunit, a trip lever mounted on secured thereto, ribs arranged on the theend otone rod, a movable casing, nieinbers termed integral with theeasing and pivotally mounted on the lower ends Sof said ribs` andportions formed in the members and adapted .to engage the eccentrics ofthe rotatable rods, `and a spring` on one of said rods adapted to raisethenio vable casing, and weather stripping secured l,in the lower end otthe movable casing.

ln testimony whereof we have hereunto set our hands inpresence of twosubscribing witnesses.
